1. Vibroacoustic performance of wooden buildings : Prediction and Perception
Sammanfattning : When the Swedish building regulations in 1994 allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, as well as wood being a plentiful resource in Sweden. However, complaints amid inhabitants are often reported due to nuisances caused by disturbing vibrations and noise propagating in the building. LÄS MER
2. Floor vibration : dynamic properties and subjective perception
Sammanfattning : This thesis covers research in the floor vibration field. Although lightweight steel framed constructions have been in focus, many results are applicable to floors in common and to some extent also to vibrations in general. LÄS MER
3. Vibrations in Lightweight Buildings - Perception and Prediction
Sammanfattning : When the Swedish construction code (in 1994) allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, and also because wood is a plentiful resource in Sweden. Drawbacks in such buildings are disturbing vibrations and noise propagating in the construction, especially through junctions. LÄS MER
4. Vibrations in a Built Environment : Prediction and Reduction
Sammanfattning : Vibrations in a built environment can exceed the requirements for sensitive equipment in a building or can cause annoyance to residents. Hence, there is often a need for reducing such vibrations. The vibrations can originate from ambient sources such as motorway traffic, or from internal sources such as people walking inside the building. LÄS MER
5. Truck Tyre Vibration Behaviour. Measurements and High Frequency Modelling
Sammanfattning : To facilitate tyre-road noise prediction, a computationally efficient high frequency tyre model is needed. Such models are always a compromise between the desired accuracy and the need for simplicity. In addition the accuracy of models is often limited by the quality of the input data available. LÄS MER
